4.1 The gasket factors are a function of leak rate; therefore, this practice generates curves. Constants for use in the ASME Boiler and Pressure Vessel Code, Section VIII, Appendix 2 code calculations are selected from these data. Specific 4.2 This practice determines two general characteristics that are specific to the ASME design criteria. Caution should be exercised when comparing yield and maintenance factors between gasket materials, and it is recommended that the 4.3 This practice builds upon work conducted in the Fluid Sealing Association (FSA G 605:11). The associated round robin data is provided for reference in Tables 1-4. 1.1 This practice will establish criteria
for determining loading constants that are referenced in the
American Society of Mechanical Engineers (ASME) pressure vessel
design (Boiler and Pressure Vessel Code, Section VIII, Divs. 1 and
2). These constants are specific to this design criterion for
metallic, semi-metallic, and nonmetallic gaskets.
1.2 Units—The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. |
